TS代码

<script setup lang="ts">
import Sortable from "sortablejs";
import {nextTick, onMounted, ref} from "vue";


const tableData = ref([
  {
    id: 1,
    order: 1,
    name: "胡大1"
  },
  {
    id: 2,
    order: 2,
    name: "王二2"
  },
  {
    id: 3,
    order: 3,
    name: "张三3"
  },
])


onMounted(() => {
  nextTick(() => {
    initDropTable()
  })
})

const initDropTable = () => {
  const sortable1 = Sortable.create(
      document.querySelector(".form_table .el-table__body-wrapper tbody") as any,
      {
        handle: ".move-icon",
        onEnd: (event) => {
          const {newIndex, oldIndex} = event
          //截取被移动的数据
          const currRow = tableData.value.splice(oldIndex as any, 1)[0]
          //将被移动的数据,插入到移动的位置
          tableData.value.splice(newIndex as any, 0, currRow)
          //数据处理(复制一份,再对order(自定义排序字段)进行赋值,然后覆盖原数据)
          let arr = Array.from(tableData.value);
          tableData.value = arr.map((item, index) => {
            return {
              order: index,
              id: item.id,
              name: item.name
            }
          })

        },
        onStart: (start) => {
          // console.log("开始:", start)
        }
      }
  );
}

function updateSort(){
  // axios...... tableData已经是最新排序数据了, 根据后端接口处理数据格式后,进行修改即可
}
